Have you ever heard of Unf*ck Your Habitat? I think it's on Tumblr. You do what's called a 20/10--work for 20 minutes, then take a 20 minute break. And so on.
I haven't done it much, but when I did it made a big difference.
ejchase, I too have trouble with feeling overwhelmed. Everywhere I look, there's clutter. Sometimes I don't know what to do with items. Regarding that issue, there's a blog called "A Slob Comes Clean" and she has a couple of Rules for Decluttering that make a lot of sense:
If I needed this item, where would I look for it? (take it there)
If I needed this item, would it ever occur to me that I already have one? (If not, get rid of it because I’d just buy a new one if I needed it.)
Unlike some other advice, this really whittles it down to the basics.
Good luck (to all of us!).
